Not at all. The guy just has to know what he's doing - full range of motion, explosiveness, etc. I think what 2B is doing now with his strength trainer will just build on what he did in the fall with the speed coach. The thing about the speed coach is that there are techniques to running, and to running the 60 especially, that this guy was very familiar with. There's a good thread about speed in the HSBBW somewhere. But I believe strength will help speed, too.
